Facebook Cookies Work Even If You're Logged Out (for Your Own Good)

Facebook may not be planning to shut down your account or charge you, but that doesn't mean that they aren't doing some things that you might want to be concerned about. Say, for example, tracking users even after they log out of the site.

That's the accusation from developer Nik Cubrilovic, who discovered that Facebook "alters" tracking cookies when you log out instead of deleting them. "With my browser logged out of Facebook, whenever I visit any page with a Facebook like button, or share button, or any other widget, the information, including my account ID, is still being sent to Facebook," Cubrilovic wrote. "The only solution to Facebook not knowing who you are is to delete all Facebook cookies."

You can delete them yourselves if anyone is that worried about it. You can even set your browser to delete everything when you close it.

That seems less secure. By leaving the cookies around without logging in to facebook, someone could easily take or copy your cookies and break your facebook account OR do fake ad clicking using your cookie to generate advertising revenue. Here's an update if anyone else is interested in fb cookies - http://www.zdnet.com/blog/facebook/facebook-fixes-cookie-behavior-after-logging-out/4120

Everyone should set their computers to delete history and cookies upon the exit of their browser. This way, it's automatic.
If you don't want to do this, then you will have to go in and manually delete each of them, which could take a lot of time, depending on how long it's been since you did it last.

They can be deleted all at once, not one at a time. But that could be done also.

You have to do cookies seperate from history.
I can't believe you didn't understand that!
However, this is why some people shouldn't have computers. They're not willing to take the time to learn to operate them properly and safely. Then they want to complain when they don't work right or they get infected with viruses and malware!
